Guard cable for road

Abstract

A guard cable for a road, includes a plurality of wire ropes extending in a horizontal direction with respect to a plurality of supports provided on the side of the road at intervals. The wire ropes are shifted to a predetermined width from the supports to the roadway by a wire rope protrusion installation unit. The plurality of wire ropes provided between the supports are maintained at constant intervals by an interval maintenance plate.

The invention claimed is: 
     
       1. A guard cable for a road in which a plurality of supports are installed at a gap at the roadside and in which wire ropes of several lines are parallelly extended in a lengthwise direction between each of the supports, wherein a receiving groove in which the wire rope is received at a front surface is located so that a wire rope support formed in a lengthwise direction of the wire rope protrudes from the support to the roadside and thus each wire rope is protruded from the support to the roadside, and in a state in which the wire rope is received at the receiving groove, a wire rope holder is installed in the support in a state that encloses the wire rope support comprising the wire rope,
 wherein a rear protrusion is formed at a rear side of the wire rope support, and in a clamp corresponding thereto, a groove that receives the rear protrusion of the rear side of the wire rope support is formed. 
 
     
     
       2. The guard cable of  claim 1 , wherein in each of the plurality of supports, an inward groove is formed in a vertical lengthwise direction, and in an inlet of the inward groove, the clamp that fastens the wire rope holder is installed, and at both ends of the clamp, an opening groove that receives a fastening device for fastening to the wire rope holder is formed. 
     
     
       3. The guard cable of  claim 1 , wherein at the inside of the wire rope holder and the receiving groove, uneven portions that prevent the wire rope from sliding are each formed. 
     
     
       4. The guard cable of  claim 1 , further comprising a fixing screw having the front end that close contacts with a wire rope received at the receiving groove by penetrating the wire rope holder. 
     
     
       5. The guard cable of  claim 1 , further comprising a gap holder that holds the parallelly extended wire ropes at a constant gap,
 wherein the gap holder couples the clamp formed to enclose each of wire ropes with the wire ropes interposed therebetween to a support with a fixing member in a state in which the support simultaneously supports the wire ropes. 
 
     
     
       6. The guard cable of  claim 1 , further comprising an auxiliary support installed at a predetermined gap from the plurality of support installed at both side end portions or one side end portion of the supports,
 wherein a pulling device of a turnbuckle form is connected between the support of the end portion side and the auxiliary support, and a connector is installed by a fixing member between both end portions of the pulling device and the support and the auxiliary support corresponding to the both end portions. 
 
     
     
       7. The guard cable of  claim 1 , wherein both end portions of each wire rope are coupled to an end portion of a splicer that penetrates a support of the end portion side of both sides.
